Screen gets locked very soon

Despite having the settings set to the longest period for screen time out , the screen goes into dark or locked mode for some reason. I am not sure its a bug. :confused:

Build : 2.1.0.0 - prerelease
platform version : 33.0a1
Build identifier 20140620035949

Just to add my battery is 100 % charged. Power save mode is disabled and turn on automatically is set to never.

Well , yes it is . even if you set the screensaver to never it still locks ( while typing )

I observed the same and a temporary solution was to use 10 minutes on my ZTE Open. In tablet nothing works. :frowning:
